Overview:
Lithops gesineae de Boer, commonly known as "living stones", is a rare succulent plant native to South Africa. The plant is a member of the genus Lithops, which consists of fascinating, decorative, and miniature plants that grow in rocky, barren areas. The plant was first described by Jan M.C. de Boer in 1960 and was named after Gesine Leeuwenberg - the wife of the well-known Dutch botanist Jan Leewuenberg.
General Appearance:
The Lithops gesineae de Boer is a small, slow-growing, low-maintenance plant that requires little attention. The plant has no stem and grows flush with the ground. It is composed of two fleshy, compressed leaves that mimic small stones, hence the name "living stones". The leaves come in various colors, including shades of grey, green, brown, and purple, which blend in with its rocky surroundings. The plant also produces yellow, daisy-like flowers that emerge from the space between the leaves.
Common Names:
The Lithops gesineae de Boer is commonly referred to by a variety of common names, including "Living Stones", "Stoneface", "Split-rock", and "Pebble Plants".
Uses:
Lithops gesineae de Boer is a decorative plant that can be used to add interest to a rock garden, container garden, or xeriscape landscape. The plant requires minimal watering and can thrive in harsh and dry conditions, making it an ideal choice for low-maintenance gardening. However, the plant is not recommended for consumption, as it contains chemicals that can be harmful to humans and animals if ingested.
Light Conditions
Lithops gesineae de Boer require bright light but must be protected from direct sunlight. Exposing them to direct sunlight may result in scorching or permanent damage to the plant. Indoor growers can place these plants near a south-facing window, and outdoor growers may use light shade to protect them from the sun.
Temperature
These plants prefer temperatures ranging from 60°F to 85°F (15°C to 29.5°C) during their growing season. Extreme temperature fluctuations may cause the plant to shrivel or become stunted. During the winter period, Lithops gesineae de Boer is known to survive in temperatures as low as 40°F (4°C).
Soil Requirements
Lithops gesineae de Boer require soil that is porous and well-draining. It is necessary to use a potting mixture with a high percentage of grit and sand. A mixture of one part potting soil, one part coarse sand, and one part pumice is ideal for promoting healthy root growth. The potting mixture should have a slightly acidic to neutral pH level ranging from 6.0 to 7.0.
The planting container should have sufficient drainage holes to prevent standing water. Overwatering can lead to root rot and may harm the plant. Additionally, Lithops gesineae de Boer is drought-resistant; therefore, growers should practice controlled watering, allowing the soil to dry out completely before watering again.
Cultivation of Lithops gesineae de Boer
Lithops gesineae de Boer are unique and beautiful succulent plants that require good sunlight and sandy soil to grow well. The plant is native to South Africa, and it is also known as "living stones" because its leaves are interestingly shaped to look like stones. It is best to cultivate Lithops gesineae de Boer in small pots that have good drainage and airflow to ensure proper growth.
Watering Needs for Lithops gesineae de Boer
Watering Lithops gesineae de Boer can be a bit tricky, as too much water can quickly cause root rot. It is best to water occasionally and deeply to ensure that the plant's roots receive enough water to grow. During the growth season, which is typically in the spring and late fall, it is recommended to water Lithops gesineae de Boer once every two weeks. However, it is essential to note that this plant prefers almost complete dryness during its dormant season in the summer.
Fertilization of Lithops gesineae de Boer
Lithops gesineae de Boer doesn't require much fertilizer to grow. However, it won't hurt if you mix in some slow-release granular fertilizer into the soil once during the growth season. Alternatively, you can dilute a liquid fertilizer and use it to water your Lithops gesineae de Boer once a month. Be sure not to over-fertilize the plant as it is susceptible to salt buildup, which can damage its roots.
Pruning of Lithops gesineae de Boer
Pruning is not necessary for Lithops gesineae de Boer as the plant grows naturally to a small size. However, you can remove any dead leaves to maintain the plant's aesthetic appeal. A gentle touch is recommended as the plant's leaves are fragile and can bruise easily.
Propagation of Lithops gesineae de Boer
Lithops gesineae de Boer, also known as Livingstone daisies, are small succulent plants that form groups of pebble-like leaves. Propagation is an essential aspect of keeping Lithops gesineae de Boer healthy and growing. Here are the four methods of propagating Lithops gesineae de Boer:
Leaf cuttings
The most popular method of propagating Lithops gesineae de Boer is through leaf cuttings. This method allows the grower to produce genetically identical offspring from a parent plant. The process involves cutting a healthy leaf using a sharp, sterilized blade and then leaving the cutting aside to dry for three days. Once the cuttings have dried, plant them in propagating soil and water them regularly.
Seeds
Propagating Lithops gesineae de Boer by seed is the most natural way of growing new plants. The process involves collecting mature seeds from the parent plant and planting them in propagating soil. The soil should be kept moist until the seeds germinate in two to four weeks. Once the seeds have germinated, allow the plants to grow to about 0.4 inches before transplanting them.
Division
Propagation of Lithops gesineae de Boer through division involves separating the offsets from the parent plant. This is a popular method for species that form clusters, such as Lithops dorotheae. Carefully remove the offsets from the parent plant and let them dry for three days. Once dry, plant them in propagating soil and water them regularly.
Grafting
Grafting is a method of propagation used to produce hybrids. The method involves attaching a scion from the parent plant to the rootstock of another plant, which acts as a support system. This method is usually done with the help of a professional and requires a lot of expertise in plant propagation.
Disease and Pest Management for Lithops gesineae de Boer
Lithops gesineae de Boer is a rare succulent plant that is generally easy to care for. However, like all plants, it is susceptible to various pests and diseases that may cause damage. The good news is that most problems are avoidable or can be easily solved with proper plant care and the timely use of appropriate pest control measures. Here are some common diseases and pests that might affect your Lithops gesineae de Boer and their management.
Common Diseases
Lithops gesineae de Boer is typically resistant to diseases but may occasionally suffer from fungal infections when overwatered, particularly during cooler months. A telltale sign of fungal infection is when the plant's leaves turn a yellow or brown color, become mushy, and eventually rot. The most common fungi that may infect your Lithops gesineae de Boer are Fusarium, Pythium, and Rhizoctonia.
To manage fungal infections, you must first remove the infected plants and avoid overwatering the remaining ones. You may use an appropriate fungicide, particularly one whose active ingredient contains copper, to prevent further spread of the infection. You may also reduce the humidity levels surrounding your Lithops gesineae de Boer by increasing ventilation and reducing moisture in the soil.
Common Pests
Despite being easy to care for, Lithops gesineae de Boer may become infested with various pests, including aphids, mealybugs, and spider mites, among others. These pests usually target the plant's top layer, where they thrive on sap and juices that eventually cause scarring and damage to the leaves.
To prevent pest infestations, always ensure that you keep your Lithops gesineae de Boer clean and healthy by removing debris, pruning diseased parts, and avoiding overfertilizing or overwatering. When you notice any pest infestation, you should immediately inspect, isolate, and remove the affected plant from the rest. Various methods may be used to control pests, including the use of insecticidal soap, neem oil, or a mix of 1:1 rubbing alcohol and water in a spray bottle.
Remember that proper plant care is key to keeping your Lithops gesineae de Boer healthy and pest-free. Always consult with a plant specialist or horticulturalist if the problem persists after applying standard pest control measures.
